Application filed April 24, 1915. Serial No. 23,564.

To all whom it may concern:

Be it known that we, JOHN J ANUCHOWSKY and HEINRICH ALBERT, citizens of the United States of America, and residents of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Bottle-Capping Machines, of which the following is a specification.

The primary object. of this invention is to ing operation.

Other and further objects will appear in the specification, and be specifically pointed out in the appended claims, reference being' had to the accompanying drawings exemplifying the invention, and in which,

Figure 1 is a sectional view, showing this improved device attached to one end of a spindle, the parts thereof being shown in inoperative position. Fig. 2- is a sectional view, similar to Fig. 1, but showing the parts of the device in an operative position. Fig. 3 is a horizontal section taken on the line III- H1, Fig. 1. Fig. 4 is an enlarged perspective of one of the adjustable cappressing members. Fig.5 is a vertical sectime taken on the line V' V, Fig. 1.

Referring to the drawings: 1 designates the lower end of a spindle, which is threaded at 2, and adapted to support a bottle cap ping head 3. Formed in the under side of said head is a chamber 4. The upper end wall 5 of said chamber has a concentric opening 6 formed therein. The side wall 7 of this chamber 4 is tapered and of a coneshape, the upper end of said chamber being much less in diameter than its lower end.

Extending inwardly from the side wall 7, at the lower end of the chamber 4, is an annular shoulder 8, said shoulder forming a cap receiving throat 9. Formed in the side wall 7 of the chamber 4 is a series of radially arranged vertical slots 10. Radially arranged against the inner surface 11 of the wall 7 are a series of cap pressing members 12, each of said members having a guiding portion 13 formed thereon. Each gulding portion of each member is engaged in'one of the slots 10. A cap screw 14 is carried by each of said guiding portions 13, said cap screws adapted to have their heads bear against the outer surface 15 of the wall 7.

Mounted in the opening 6 of the end wall 5 is a plunger 16. Formed on the upper end of said plunger is a spring seat 17, which is adapted to receive a pressure spring 18. Formed on the plunger 16, and located in the chamber 4, is an annular shoulder 19. The under side of said shoulder is adapted to bear against the upper side of the horizontal portion 20 of each cap pressing member 12. This plunger 16 is preferably constructed insections, there being an upper section 21, and a lower section 22, said sections being secured together by the centrally arranged screw 23. Formed in the lower section 22 is a shoulder 24. Said shoulders 19 and 24 of said plunger 16 form a reduced neck portion 25. The space provided 19 and 24: is adapted to receive the horizontal portions 20 of the cap pressing memhers-12. Each of the cap pressing members 12 has a depending portion 26. Each of said portions 26 of'said pressing members has a cap receiving face 27.

Horizontally and radially arranged in the annular shoulder 8 are a plurality of spring-pressed plunger-s 28, said plungers being reciprocably mounted in the chambers 29. 'Each of said chambers is closed at one end by a screw 30.

In the operation of this improved bottle capping mechanism, when the pressing members 12 are inactive, the depending portions 26 thereof will rest on the shoulder 8 (see Fig. 1). In this construction, the embodiment shown relates to the capping or sealing of milk bottles. When it is desired to seal a bottle, a cap 31 is engaged in the against the under side of the cap 31. The

elevating mechanism may, for instance, consist of a foot treadle-or any other reciprocating mechanism, operating directly or through the intermediary of a yielding means, to raise the platform 35, and the slight variation in the travel of the platform, required for ".diiferent sizes of bottles, may obviously be regulated in this manner. Such commonly known mechanisms are shown and described, for instance, in-U. S.

31 will be disengaged from'the'plungers 28,

- and will be carried upwardly until the top 1 of said capengages against the under side of the lower section 22 of the plunger 16.

the upward movement ofthe bottle will If, in the meantime, thecap has not become fully seated on the mouth portion 33 of the bottle, theaction of the spring 18- upon the plunger 16 against the cap, and

cause saidcap to be seated in proper position on the bottle, and the top edge ofthe bottle mouth will firmly engage the under side of the top of the cap. As the upward movement of the bottle is continued, the plunger 16 will be elevated against the pressure of the spring 18, and theupper surface of the shoulder 24,-will engage against the under side of the horizontal portions 20 of the cap pressing members 12, thereby carrying said members upwardly, As said cap pressing members are being elevated, said members will be carried inwardly on account of their engagement with the tapering -inner surface 11 of the side walls 7 of the chamber 4. As the members 12 are moved inwardly, the cap engaging faces 27 of said members will eventuallyengage the depend ing flange 32 of said cap, and will firmly press said depending flange against the outside wall of the head of the bottle neck (see Fig. 2). After this has been done, it is seen that said members 12 cannotbe moved any farther inwardly and upwardly. 'After the cap has been secured to the bottle, as just described, the platform 35 is lowered, thereby removing the resistance of the bottle against the cap pressing members 12', and

said members will return to their original positions in the slots 10, bytheir own Weight,

or-by the pressure of the spring 18 against '-movement, the supposition being that the bottle shown in said view is of the. smallest caliber. If a bottle having a larger diameter across the beaded neck than that shown were operated on by said members'12, said members would not travel as far upwardly as the position shown, because the faces side of the bottle neck before said members reached their limited traveling position. This arrangement of slidingly mount-.

ed cap" pressing members 12, which are adapted to travel inwardly as they travel upwardly, provides means of securing the. .Patents Nos. 985,141 and 949,678. Asthen elevating of the bottle is continued, the cap.
